SPATIAL PROFILING SYSTEM AND METHOD

摘要

Described herein is a system, a method and a processor-readable medium for spatial profiling. In one arrangement, the described system includes a light source configured to provide outgoing light having at least one time-varying attribute at a selected one of multiple wavelength channels, the at least one time-varying attribute includes either or both of (a) a time-varying intensity profile and (b) a time-varying frequency deviation, a beam director configured to spatially direct the outgoing light into one of multiple directions in two dimensions into an environment having a spatial profile, the one of the multiple directions corresponding to the selected one of the multiple wavelength channels, a light receiver configured to receive at least part of the outgoing light reflected by the environment, and a processing unit configured to determine at least one characteristic associated with the at least one time-varying attribute of the reflected light at the selected one of the multiple wavelengths for estimation of the spatial profile of the environment associated with the corresponding one of the multiple directions.

1. A spatial profiling system including:
a light source configured to provide outgoing light having at least one time-varying attribute at a selected one of multiple wavelength channels, the at least one time-varying attribute includes either or both of (a) a time-varying intensity profile and (b) a time-varying frequency deviation; a beam director configured to spatially direct the outgoing light into one of multiple directions in two dimensions into an environment having a spatial profile, the one of the multiple directions corresponding to the selected one of the multiple wavelength channels; a light receiver configured to receive at least part of the outgoing light reflected by the environment; and a processing unit configured to determine at least one characteristic associated with the at least one time-varying attribute of the reflected light for estimation of the spatial profile of the environment associated with the corresponding one of the multiple directions, wherein the light receiver is configured to inhibit detection of non-reflected light based on a difference in wavelength or modulation between the outgoing light and the non-reflected light.
